To all whom tt may concern: I

Be it known that ILMARK L. Dnnnme, of

Cleveland, in the county of 'Ouyahoga and State of Ohio, have inventednew and useful Improvements in the-Manufacture of Paper Bags,

of which the following is a description.

The nature of this invention relates to forming the bottoms of paperbags so that said bags when distended shall have flat bottoms of arectangular form orf'which to stand erect.

. and unsupported when filled. "A full and complete description of themanner of forming the said bottom of the bag is as follows, referencebeing had to the accompanying drawings for illustrating the variousfoldings of the paper The outlines of Figure 1 represent a sheet ofpaper or blank of which to make a bag;

The several lines drawn across the blank indigether, or nearlyso. Fig. 3is an edge view of the tube or body of the bag when distended. Fig. 4 isa view of the tube or body of the bag in the second folding of theprocess of forming the bottom. Fig. 5 shows the third folding in theprocess, and which represents the sides of the tube or bag as compressedtogether. Fig.

' 6 shows an edge view of the tube or bag Fig. 5 when distended. Fig. 7shows an edge view has.

of the bag Fig. 6 when partially compressed together. Fig. 8 shows anedge view of the tube, Fig. 6, when-wholly compressed-that is to say,flattened down. Fig.9 shows the fourth folding of the tube or bag in theprocess of forming the bottom. Fig. 10 shows the fifth.

folding, which; completes the bag. Fig. 11 is an. inside view of thefolding shown in Fig. 5. Fig. 12 is a perspective view of a bag, the up"per portion of which is represented as torn off for convenience, and soof the other figures on Plate 2.

Like letters of reference refer to like parts in the several views. y

In order to make the above-said bag a sheet of paper, termed a-blank,(which is represented by the outlines A in Fig. 1,) is folded by anysuitable'means in direction of the lines B and G. The lines B form thecorners D,

Fig. 12, of the bag. This folding is the first in theproce'ss'of makingthe bag. .The two sides A A of the blank are thenbrought together andlapped upon each other, as seen at A Fig. 2,'and secured by pasting orotherwlse.

The dotted lines 0 iii-Fig. 2 correspond to the lines 0 in Figs. 1 and3. The body of the bag thus formed by the folds B (J andlapping of thesides A is a rectangular tube when distended, as shown in Fig. 3, andwhen the sides are compressed together, as shown in Fig. 2,

the lines 0 in Fig. l formthe folds O in said Fig. 2. This completes thefirst foldings in the process of making the bag.

The bottom'is now to be made. To this endv a certain portion of one endof the tube, on being compressed together, is creased and donbled backonto the bag, making a lap, E, Fig. 4, and the crease a in-Fig. 6. Thismakes-the second folding in the process. The third fold is made byturning-the lap E up at about right angle to the body of the bag'anddistcnding it, as shown in Fig. 5,

then forming across the ends of the upturned lap a crease, F, Fig. 6, bypushing inward the material above the crease, and folding it down uponthe bag, making the laps G G, Fig. 5, both of which are alike. One endof the laps lies upon the bag above the crease a of the lap E, as seenat b. The other end of said laps extends below said crease, as shown atc in said Fig. 5. This manipulation of the bag not only forms the twolaps G G, but also the triangle lar folds H, Figs. 6 and 11, (shown alsoin Fig. 5.) A portion of the lap G is represented as torn away, that thetriangular fold may be seen.

The'fourth fold in the process is made by folding the lower parts of thelaps G. along the line 0, Fig. 5, and doubling it down upon the'bag,forming the lap I, Fig. 9, which is secured in place by the applicationof'paste along the edge of the lap.

The fifth fold is made in like manner by folding over ontoithc lap I theupper part of the laps G G, which is folded along the crease m, Fig. 5,forming the lap J, Fig. 10, which in like manner is secured with pasteapplied to the edges of the lap. It is not essential. that the lap I befirst made. The lap J may be made first, and the lap I doubled onto it.This last folding completes the bottom of the bag, an external View ofwhich is shown in said Fig. 10. 5 A perspective view of the bag'wheudistended is shown in Fig. 12, the upper part of which is shown as tornoff for conyeuience;

In making bags it isnot necessary that" a singleisheet or blank shouldbe used for each 10 bag. A long strip of paper may be treated with thefirst foldings (and pasted, as herein described) of the blank Fig. 1,thereby forrniu g a long tube, which may be cut into lengths for bags.15 The bag herein described is represented as of an oblong square. Bags,however, of other rectangular forms can be made by the same or similarfoldings and laps without changing the nature of the invention.

-What I claim as my invention, and desire 20 to secure by LettersPatent, is
